Delta-sleep-inducing peptide (DSIP) as a factor facilitating animals' resistance to acute emotional stress

K V Sudakov et al. Pavlov J Biol Sci. 1983 Jan-Mar.

Abstract

Delta-sleep-inducing peptide (DSIP) effects on resistance to acute emotional stress induced by electric stimulation of the ventromedial hypothalamus and skin of immobilized rats have been investigated. On the basis of the pattern of cardiovascular reactions, three groups of rats were distinguished: resistant, adapted, and predisposed to the experimental emotional stress. It is shown that DSIP injections increase animals' resistance to acute emotional stress. DSIP also changes the vascular reactivity to episodic emotiogenic stimulations. It is revealed that, after DSIP application, the absence of vascular reactions to emotiogenic ventromedial hypothalamic and electro-skin stimulations significantly increased.
